Change History

I've made a prototype of this feature and works fine, however I would like some input on how exactly it should work. Adding it in the details is kind of pointless as generally the Video: tag indicates the resolution. I was thinking that it could be treated similar to a favorite, where it is non-visual meta data allowing the filtering of of the episodes/movies etc. I think that it should be a non-radio style check box in addition to the filters, similar to the sort-by flags.

Another question that I have yet to resolve is what does everyone consider hi-def ?

Greater than 480?
Many 720p movies are letterboxed and so they have resolutions as low as 528.

When it comes to the data-model, would people prefer that I store the resolution directly or a simple hi-def flag?
